Oral allergies represent a pathological entity not well known nor diagnosed by dental health professionals. The purpose of this work is to present an information relative to the multidisciplinary steps to be done to solve allergy problems. Three clinical examples of contact oral allergies (to mercury, or gold, or methacrylates) are presented, as to illustrate signs and symptoms of an oral allergy to the more frequent dental materials implied.We discuss the problem of oral allergies from what is known from the scientific literature. We stress the importance of a multidisciplinary approach to take into account patients with an oral allergy, with participation of specialists from dental and dermatologic fields.

Background: Positive findings from the phase III MPACT trial led to the regulatory approval of nab-paclitaxel plus gemcitabine as a treatment option for patients with metastatic pancreatic cancer. This report is an update of overall survival (OS) based on longer follow-up. Methods: Patients (n = 861) with metastatic pancreatic cancer and a Karnofsky performance status of 70 or greater were randomly assigned one to one to receive nab-paclitaxel + gemcitabine or gemcitabine alone. Efficacy data for this post hoc analysis were collected through May 9, 2013. Exploratory analyses of carbohydrate antigen 19-9 (CA19-9) and neutrophil-to-lymphocyte ratio (NLR) were conducted. The primary efficacy endpoint was OS, which was analyzed for all randomly assigned patients by the Kaplan-Meier method. All statistical tests were two-sided. Results: The median OS was statistically significantly longer for nab-paclitaxel plus gemcitabine vs gemcitabine alone (8.7 vs 6.6 months, hazard ratio [HR] = 0.72, 95% confidence interval [CI] = 0.62 to 0.83, P <. 001). Long-term (>three-year) survivors were identified in the nab-paclitaxel plus gemcitabine arm only (4%). In pooled treatment arm analyses, higher CA19-9 level and NLR at baseline were statistically significantly associated with worse OS. There appeared to be a treatment effect for OS favoring nab-paclitaxel plus gemcitabine over gemcitabine alone in poor-prognosis subgroups defined by these factors (HR = 0.612, P <. 001 for CA19-9 level ≥ median and HR = 0.81, P =. 079 for NLR > 5). Conclusions: These data confirm and extend the primary report of OS, supporting the superior efficacy of nab-paclitaxel plus gemcitabine over gemcitabine alone. Subgroup analyses support the relevance of CA 19-9 and NLR as prognostic markers in metastatic pancreatic cancer. © The Author 2015. Published by Oxford University Press. All rights reserved.

Context: Penile curvature can be congenital or acquired. Acquired curvature is secondary due to La Peyronie (Peyronie's) disease. Objective: To provide clinical guidelines on the diagnosis and treatment of penile curvature. Evidence acquisition: A systematic literature search on the epidemiology, diagnosis, and treatment of penile curvature was performed. Articles with the highest evidence available were selected and formed the basis for assigning levels of evidence and grades of recommendations. Evidence synthesis: The pathogenesis of congenital penile curvature is unknown. Peyronie's disease is a poorly understood connective tissue disorder most commonly attributed to repetitive microvascular injury or trauma during intercourse. Diagnosis is based on medical and sexual histories, which are sufficient to establish the diagnosis. Physical examination includes assessment of palpable nodules and penile length. Curvature is best documented by a self-photograph or pharmacologically induced erection. The only treatment option for congenital penile curvature is surgery based on plication techniques. Conservative treatment for Peyronie's disease is associated with poor outcomes. Pharmacotherapy includes oral potassium para-aminobenzoate, intralesional treatment with verapamil, clostridial collagenase or interferon, topical verapamil gel, and iontophoresis with verapamil and dexamethasone. They can be efficacious in some patients, but none of these options carry a grade A recommendation. Steroids, vitamin E, and tamoxifen cannot be recommended. Extracorporeal shock wave treatment and penile traction devices may only be used to treat penile pain and reduce penile deformity, respectively. Surgery is indicated when Peyronie's disease is stable for at least 3 mo. Tunical shortening procedures, especially plication techniques, are the first treatment options. Tunical lengthening procedures are preferred in more severe curvatures or in complex deformities. Penile prosthesis implantation is recommended in patients with erectile dysfunction not responding to pharmacotherapy. Conclusions: These European Association of Urology (EAU) guidelines summarise the present information on penile curvature.

Objective: To report short- and long-term effects of an audit process intended to optimise the radiation dose from multi-detector row computed tomography (MDCT). Methods: A survey of radiation dose from all eight MDCT departments in the state of Luxembourg performed in 2007 served as baseline, and involved the most frequently imaged regions (head, sinus, cervical spine, thorax, abdomen, and lumbar spine). CT dose index volume (CTDIvol), dose-length product per acquisition (DLP/acq), and DLP per examination (DLP/exa) were recorded, and their mean, median, 25th and 75th percentiles compared. In 2008, an audit conducted in each department helped to optimise doses. In 2009 and 2010, two further surveys evaluated the audit's impact on the dose delivered. Results: Between 2007 and 2009, DLP/exa significantly decreased by 32-69% for all regions (P <0.001) except the lumbar spine (5%, P =0.455). Between 2009 and 2010, DLP/exa significantly decreased by 13-18% for sinus, cervical and lumbar spine (P ranging from 0.016 to less than 0.001). Between 2007 and 2010, DLP/exa significantly decreased for all regions (18-75%, P <0.001). Collective dose decreased by 30% and the 75th percentile (diagnostic reference level, DRL) by 20-78%. Conclusions: The audit process resulted in long-lasting dose reduction, with DRLs reduced by 20 -78%, mean DLP/examination by 18-75%, and collective dose by 30%. Key points: • External support through clinical audit may optimise default parameters of routine CT. • Reduction of 75th percentiles used as reference diagnostic levels is 18 -75%. • The effect of this audit is sustainable over time. • Dose savings through optimisation can be added to those achievable through CT. © European Society of Radiology 2013.

PURPOSE OF REVIEW: Ataxia is the predominant manifestation of many acquired and inherited neurologic disorders affecting the cerebellum, its connections, and the afferent proprioceptive pathways. This article reviews the phenomenology and etiologies of cerebellar and afferent ataxias and provides indications for a rational approach to diagnosis and management. RECENT FINDINGS: The pathophysiology of ataxia is being progressively understood and linked to the functional organization of the cerebellum. The impact of cerebellar diseases on different neurologic functions has been better defined and shown not to be limited to loss of motor coordination. The role of autoimmunity is increasingly recognized as a cause of sporadic cases of ataxia. Large collaborative studies of long duration are providing crucial information on the clinical spectrum and natural history of both sporadic ataxias (such as the cerebellar form of multiple system atrophy) and inherited ataxias. New dominant and recessive ataxia genes have been identified. On the therapeutic front, progress mostly concerns the development of treatments for Friedreich ataxia. SUMMARY: Ataxia is the clinical manifestation of a wide range of disorders. In addition to accurate clinical assessment, MRI plays a major role in the diagnostic workup, allowing us to distinguish degenerative conditions from those due to other types of structural damage to the cerebellar or proprioceptive systems. Diagnostic algorithms based on clinical features, imaging, and neurophysiologic and biochemical parameters can be used to guide genetic testing for hereditary ataxias, the diagnosis of which is likely to be greatly improved by the introduction of new-generation DNA-sequencing approaches. Some rare forms of ataxia can be treated, so their diagnosis should not be missed. Proven symptomatic treatments for ataxia are still lacking, but intensive physical therapy appears to be helpful.
